FIRELESS comma.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed March 12, 1915. Serial N 0. 14,026.

To all whom it may concern:

Be it known that'I, HUGO Moon, a citizen of the United States of America, residing at New Brighton, in the county of Rich-' mental in appearance and eflicient'in conduction and radiation of heat from the cooking utensil. I

In the drawings, Figure l presents a ver tical sectional view through i the cooker showing-the parts assembled, Fig. 2 showsv a horizontal section view as on the line 22 of Fig. 1, and'cFig. *3 shows a similar view as on the line 33 of Fig. 1.

Essentially the device consists of a series of concentric bell shaped covers of varying sizes adapted to be superimposed over each other, each bell resting on abase slightly larger than the perimeter of the-bell which supports said base A having a depending flange 7) upon which the-bell l-rests The bases A are separated from each other by insulating pins C which are preferably-made of hard rubber, bone, wood or other heat non-conducting material. The bells as well as the bases upon which they rest are pref erably made of aluminum or other light metal capable of taking a high polish. Each of the bells with its appropriate base .in-

closes a certain portion of air whichacts as a non-conductor and as both its internal and externalsurfaces are highly polished, there is little radiation or conduction of heat from .one bell to the next inclosing same. As direct conduction of heat from one base to the other is prevented by insulating pins C, a

fireless cooker made in this fashion is found as equally efiicient as the cookers provided with the usual non-conducting materials. The larger these bells are made and tliemore bells that are-used, the more eflicient will be the fireless cooker on account'of inclosing a greater volume of air and on account of having a greater number of successive surfaces to prevent radiation of heat.

Having thus described my invention, what i I claim is z- 1. A fireless cooker'comprising a series of,

bell shaped metallic covers of varying sizes superimposed one upon the other, each coverresting on a metallic base. slightly larger than its diameter so as to inc'losean-air space,said covers being separated from each other bynon-metallic pins supporting said bases.

' 2. A fireless cooker comprising a series of bell shaped metallic covers of varying'sizes superimposed onejuponfthe other, each cover resting on a metallic base having a depend-' ing flange slightly larger than its. diameterv so as to inclose an air space, said covers belic pins supporting said bases. a

3. A fireless'cooke'r comprising a series of one piece bell shaped metallic covers. superimposed one upon theother, each ing separated from each other .bynon-metalcover res't ing' ona' metallic base so as to inclose an air zone, said bases .being supported by and insulated .from each other by" non-conducting" pins.

adaptedtosupport the cooking vessel, a bell shaped metallic member adapted to cover said vessel, resting on said base and forming an air zone about said vessel and a series of. metall1c covers and bases of varying sizes arranged concentrically around said vessel so as to forma series of air zones to insulate same, the bases being supported and insupins.

In testimony whereof I aiiix my signature in thepresence of two witnesses.
